If all the radio users comply with the following rules, an efficient two-way
radio communication can be achieved.

1. Do not interrupt other users to speak. Keep an eye on the call on the
channel. Most of the two-way radio pairs have a monitor button on the machine.
Press this button to hear the call on the channel. The channel before sending
must be blank.

2. Keep the walkie-talkie in the vertical position, the loudspeaker, the
microphone is kept in front of the mouth three inches.

3. Talk to the microphone slowly and clearly. Long story short, it will not
occupy the voice channel for too long.
